Abstract

A small optical system that is capable of widening an angle of view is provided. This optical system is provided with a first surface having a reflecting action and a second surface that reflects a light beam reflected on this first surface toward the first surface again. Then, a principal ray at central angle of view that is made incident on the first surface again is reflected and travels to a side opposite to a side of the last time it was reflected from the first surface with respect to a normal line of a surface at a hit point thereof. <IMAGE>
